Android Studio Gradle错误（JAVA）？

Question

enter image description here我是安卓新手。请分享解决方案。我安装了 android studio，然后在编译程序时在 Gradle 控制台中出现以下错误。

应用插件：'com.android.application'

机器人{ compileSdkVersion 23 buildToolsVersion "25.0.2"

defaultConfig {
    applicationId "com.example.global.myapplication"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

依赖{ 编译 fileTree(dir: 'libs', include: ['*.jar']) 测试编译'junit：junit：4.12' 编译'com.android.support:appcompat-v7:23.3.0' }

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

Answer 1

从错误消息中，有一行说

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.

错误是由于指定的堆大小过小。无论如何，您可以通过将其添加到您的 build.gradle 来解决此问题

android {
  dexOptions {
    javaMaxHeapSize "4g"
  }
}

请试试这个，让我知道它是否有效。

Answer 2

错误：java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : 不支持的 major.minor 版本 52.0

52.0 类版本用于 Java 1.8。看来您使用的是较低版本的 JDK。尝试将其升级到 1.8。
